Data privacy in Vehicular Ad hoc NETworks(VANET) is a practical issue currently under the research and development. Privacy preserving anonymity authentication in network is a challenging topic combining anonymity, authentication, data privacy and network. Existing anonymity authentication in VANET are based on k-anonymity model, but k-anonymity model group selection may leak information due to absence of diversity in the sensitive attribute etc., and thus group selection is a problem left unresolved. In this paper, we would like to address anonymity authentication attack issues, how to improve efficiency and sustain anonymity service using cooperation instead of zero trust model, and flexibility of vehicular side group selection to adapt changing privacy-preserving concern. Therefore, we put together design of an anonymity authentication protocol with cooperation, data privacy, and privacy-preserving data publishing considerations. Through our extensive work, we demonstrated that privacy-preserving anonymity authentication in VANET could be extended with more efficiency and cooperation plays a key role.
